To all whom it may concern Be it known that I, THOMAS NATHAN Rus- SELL, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a. new and useful Improvement in Car-Roofs, of which the following is a specification.

The invention relates to outside metal roofs for freight cars, and has for its principal object to so unite the roof sheetsand their connecting and securing parts that the roof will be water-tight and also flexible in its seams. Such flexibility prevents the roof from being damaged by the torsional strains and movements to which the frame work of the tops of freight cars are subject in service. This result is largely obtained by leaving each roof sheet or section sufficiently free and independent of other roof sheets or sections so-.that it will absorb all of the strain to which it may be subjected, without communicating such strain in any injurious degree to other parts of the metal covering. The several roof sheets have a free lateral and longitudinal movement relative to each other when the said torsional or lateral strains occur in the framework of the car,

, accompanying drawings means for carrying the same into practical effect, without limiting the improvements, in their useful application, to the particular construction which, for the purpose of example, has been delineated.

In said drawings Figure 1 is a plan view, partly broken away, of a portion of a freight car roof embodying the invention. Fig. 2 is a 'side view of thesame. Fig. 3 is a transverse vertical section of the same on line III-III of Fig. 1, the view being on a larger scale and partly broken away. Fig. 4-

is a similar view, on a still larger scale, on line IV-IV of Fig. 1; Fig. 5 is a vertical, longitudinal, sectional view of a portion of one end of the roof, on line V'-V of Fig. 1. Fig. 6 is a vertical Alongitudinal section ,across two roof sheets and their seam cap,

the sheets being part-1y broken away. Fig. 7 is a perspective view of a roof sheet. Fig. 8 is a perspective view of a seam cap, showing the end portions of the same, the intermediate portion being broken away. Fig. 9 is a perspective view of a ridge cap.

Referring to the drawings, 1 is the ridge pole of a 'freight car, 2 the side plates, 3 the carlines, 4 the top sheathing, which may run longitudinally, as shown, .or transversely of the car; 5 vthe side sheathing, 6 the fascia, 7 the walk sleepers and 8 the walk. 9 indi- Cates the end plates, and 10 the end sheathing (Fig. These parts may be of any usual or preferredv and suitable construction.'

11 indicates the roof plates, of suitable sheet metal, which arelaid side by side on the top sheathing, extending from the fascia to the ridge pole, at both sides ofthe roof. vThe roof plates are bent at their edges to form flanges whereby they are connected with the car body, and are connected loosely, flexibly or movably with each other. 12 is a downturned flange atthe lower or outer edge of the sheet which fits over the side fascia 6 o f the car. y

13 is an upturned flange at the upper or inner end of the sheet.`

14, 14 are upwardly and inwardly turned flanges at the sides of the sheet, terminating in downwardly extending edges 15, 15 so arranged as t-o leave between the parts 14 and 15 a space 16. At the corners of the inner end of the sheet the flanges 14 are united with the flange 13, the superfluous metal being Vbent and folded as indicated at 17, the corners of the sheet having first been notched. This connection closes tl ee corners and kepstlf inner end of the flange 14 at the desired inward inclination. The edges 15 pas down at the side of the flange 13, as seen in Fig. 7.

The inverted and inclined U-shaped flange,

which is thus formed by the parts 14 and 15,

is connected with the similar flange of the adjacent sheet by a seam cap (Fig. 8) which is composed of a section of sheet metal spaces'20, 20 and a middle space 21. At its inner end neXt vto the ridge pole the seam cap isv formed with a flange 22 which may be bent down to close or partly close the end of the cap and abut against the ends of the roof plate flanges 14, 15 (Figs. 4 and 8).

The seam cap` is assembled with the 'roof sheets l1, as best seen inFig. 6, by properly interlocking it with the adjacent flanges 14, l15 of. the roof sheets and then sliding it longitudinally ofmthe seam into place.` If the seam cap be so applied at the outer ends of the 'roof sheets, the flange, 22 will be bent down after the seamV cap is in place. After the parts are thus connected free movement of the roofsheets can take place in the seam cap, independent of each otherand 'of the cap. The flange edges 15 have the spaces 20 to move in, and the flanges 19 have the spaces 16 which permit the -free relative working of the parts 15, 19 and 14.

`The seam cap 18, 19'is so designedthat the sections on the under side, where the flanges turn inward, are so shaped at they .bends 23 that should a slide of ice or snow falling off a roof strike the seam, the seam will not open up and cause the roof to leak, but will cause the seam cap to close up into the corners 'of the flanges on the sheets at the bends 24, this making the seam tighter, instead of'its opening up,- as occurs with otherjty'pes of seams.

' The seam caps at opposite sides of theV ridge of the car roof are in line with each other, their ends nearly abutting as seen in Fig.'l4, space being left for the vertical se-A "curinjg bolt 25 which passes down between them; 26 Iindicates the ridge cap (Fig. 9), a series of which caps, lapping over and underl one another alternately,.extends forthe entire length of the car. at the ridge and loosely connects the roof plates at one 'side of the ridge with those at the other side. Each ridge cap is formed with a longitudinal inverted U-bend 27 which incloses the inner upstanding lianges 130i the contiguous roof plates, one at each side of the ridge. Between the ends of the bend 27 the cap is formed wit-h a short transverse inverted U- bend 28 which intersects with the bend 27 and is of such diameter as' to"inclose.the.

for thef'bolt 25. t the sides of the be 2'( are formed lianges 30 which are slightly inclined downward to correspond with the slopes of the roof. The ends of the flanges 30 remote frointhe bend 28 are turned up to form vertical (or slightly inclined from the vertical) flanges 31 which fit within the bend 28 of the next adjacent ridge cap and between the inner face of such ridge ca and the outer face of the seam cap (Fig. 2 The ridge caps are thus locked with each other against relative longitudinal displacement being also interlocked against relative lateral displacement by the lapping of the.

bends 27.

The walk sleepers 7are or may be shaped on their under sides, as by grooves, to fit over the ridge caps and seam caps and rest on the roof plates. The walk sleeper is formed with a recess 32 on its upper-side'.

to receive the head 33 'of thebolt 25.

34 is a bolt head cover'of sheet metal or water proof material fitted over the bolt head and recess to exclude rain and prevent rotting of the sleeper. The walk 8 is secured on the sleepers 7 in the usual manner. The bolts 25 pass down through the sleeper, the hole 29 in theridge cap, between the seam caps, and through the top sheathing,`

ridge pole and carline, against the under side of which latter bears its washer and nut 35.

The outer edges of the roof sheets and their depending langes 12 are clamped upon the top sheathing and against the fascia or crown molding by sheet clips 36 of malleable iron which are secured by a bolt 37, which extends to the inner side of the side plate 2, and by a wire nail 38. These clips have upwardly and inwardly inclined arms 39` which bear down on the roof sheets.

The outer end of the seam cap is hel ,within a seam cap casting 40 ofmalleabl iron, having a depending arm 41.` This anni bears against the roof sheet flange 12, and below the latter is seured Lto the car by a bolt 42k extending through to the inner s'de of the side plate, and by wire nails 43, 43

y driven into the fascia. The inward part of the casting 40 supporting the seam cap has three ribs 44, one at the top and one at each lower side, connected by avring or collar.

45 at their inner4 ends and joined at their outer ends to the arm 41. The said two ribs .44 at the sides extend downward'and inward and support the seam` cap, on the under side and hold it up to limit the4 contact of the flanges 19, at their edges, with 'the top bend of the roof sheet flange, and 'of the edges of the roof sheet langes15 with the bottom :bends ofthe seam cap. so as to prevent wear by chaiing at these points. The lateral apertures in Vthehood-portion of the casting 40, forined Aby the 44 and collar 45,l also lessen wearpon the end 'ofthe seam-cap and prevent the accumulation of moisture and cinders that would tend to rust out such y seam-cap end.

made rights and lefts, and they have only one upstanding flange 14, and at their outer slde are formed with dependimg` flanges 47 which are secured to the outer face of the end fascia 48 (Fig. '5). The outer ends of the ridge cap at the two end's of the roof are inclosed by ridge cap clips 49, which are formed with inverted U-shaped portions 50 adapted to inclose the bends 27 of the ridge caps, with horizontal or slightly inclined flanges 51 which rest on the ridge cap flanges 3() and with depending arms 52. The arm 52 is secured by bolts 53 which-pass through the end fascia and end' plate 9.
